一道英语阅读题
Everybody knows that some pars of his body like arm will become weak if he doesn't use them for some time.But when he starts using them again,they slowly become strong again.But not many people know that memory works in the same way.
Some people have good memories becasue they use (them) a lot.But some people's memories are poor because they don't give their memories enough chances to become strong.If a friend says that his arms are weak,we know that it is his own fault.But if he tells us that he has a poor memory,many of us think that his parents may be to blame,and few of us know that it is also his own fault.Have you ever found that some people can't read or write but usually they have better memories?This is because they have to memorize all the things,such as days,names,address and so on.They keep their memories working all the time.
So if you want to have a good memory,please exercise your memory as often as possible.
